摘要

PROBLEM TO BE SOLVED: To miniaturize a driving device of an ice-making dish employing a stepping motor. ;SOLUTION: The device constitutes a gear mechanism 12 of a common gear train 12a transmitting rotation of the stepping motor 11 from a pinion gear 13 to third stage gear 16, a slow gear train transmitting rotation of the third stage gear 16 from a smaller gear 16c to an ice-making dish driving shaft 21 and a high-speed gear train transmitting the rotation of the third stage gear 16 from a medium gear 16b to the ice-making dish driving shaft 21 and is configured so that the stepping motor 11 and the third stage gear 16 are located each other at a substantially opposing position as centering the ice-making dish driving shaft 21 because a transmitted gear 14 of the common gear train 12a is disposed coaxially with the ice-making dish driving shaft 21 and can arrange the stepping motor 11 at corner of the gear mechanism 12 and is such good balance that the ice-making dish driving shaft 21 is substantially centrally arranged on the gear mechanism 12 and is capable of realizing less components as well as low cost due to improvement of productivity because common connection of three gear trains constituting the gear mechanism 12 is performed by the third stage gear 16.;COPYRIGHT: (C)2003,JPO
